(b) Write a linear revenue function representing the revenue Rx (in $) for cleaning x offices per month. (c) Determine the number of offices to be cleaned per month for the company to break even. (d) If 25 offices are cleaned, will the company make money or lose money

Answer 1

Answer:

a) C(x)=50x+450

b) R(x) = 140x

c) Company will have to clean 5 offices to break even

d) Company will make money, $1,800

Step-by-step explanation:

a) C(x) = 50x+450

b) R(x)=140x

c) to break even, C(x) = R(x)

140x=50x+450

 90x=450

      x=5

Company will have to clean 5 offices to break even

d) R(x)= 140*25 = 3,500

    C (x)=50*25+450 = 1,700

    total profit will be 3500-1700 = 1,800

    so company will make money
